Brief description of the working principle of industrial dehumidifier
The working principles of industrial dehumidifiers are mainly divided into two categories: condensing type (compressor type) and rotary type.
Condensing dehumidifiers work in a similar way to the cooling and dehumidifying functions of air conditioners: a fan draws moist air into the machine, which first flows through a low-temperature evaporator. When it cools, the water vapor in the air condenses into water droplets, which drip into a drip tray and are discharged through a drainpipe.
After that, the dry cold air with moisture removed flows through the condenser and is heated to close to room temperature, and finally the dry air is sent back into the room.
Rotary dehumidifiers rely on adsorption materials to absorb moisture from the air. Their core is a honeycomb-shaped moisture-absorbing rotor, which operates in two phases: absorption and regeneration.
They are suitable for environments with low temperatures and low humidity requirements, reducing humidity to extremely low levels. However, they consume more energy.
Detailed explanation of the main drainage methods of industrial dehumidifiers
1. Gravity Drainage
Gravity drainage is the simplest and most basic drainage method, relying on the water's own gravity to flow naturally through the drainpipe.
This method requires the dehumidifier to be installed above the drain point to ensure smooth water flow.
Advantages: Simple structure, no additional energy required, low cost, and minimal maintenance.
Disadvantages: Due to the limited installation location, the drainpipe is prone to clogging due to accumulation of sludge and metallic dust.
Suitable for sites with sewers and where the dehumidifier is installed above the drain point.
2. Pump-Driven Drainage
Pump-driven drainage uses a pump to actively drain condensate outside the dehumidifier.
This method typically uses a float switch or liquid level sensor. When the water level in the drain pan or tank reaches a certain level, the pump automatically activates to drain the water.
Advantages: Flexible installation location and no height restrictions. It's particularly suitable for applications with high-level drainage and no sewers.
Disadvantages: Requires additional energy, is costly, and carries the risk of pump failure.
Useful in applications such as basements where the drain point is higher than the dehumidifier installation location.
3. Tank Collection and Drainage
Tank collection and drainage is a common drainage method for small and medium-sized dehumidifiers. Condensate is collected in the device's built-in water tank. Once the tank is full, it must be manually drained or connected to a drain pipe.
Advantages: Flexible installation, no restrictions on drainage point location.
Disadvantages: Regular manual cleaning is required, and the dehumidifier will automatically shut down when full.
Suitable for: Locations with low dehumidification capacity, low usage frequency, or as a temporary drainage solution.
4. Integrated Multi-Drainage System
Modern industrial dehumidifiers often utilize an integrated multi-drainage system, integrating multiple drainage methods into a single structure, allowing users to select different drainage modes based on their needs.
This system typically includes a drip tray, a sink, multiple drainage holes, and connecting channels, supporting various drainage methods, including natural drainage, pump drainage, and tank drainage.
Advantages: Flexible use, strong adaptability, and greatly simplified production processes.
Disadvantages: Relatively complex structure and high cost.
Suitable for: Changing environments requiring flexible drainage solutions.
Drainage Solutions for Special Environments
Basement Drainage Solutions
Basements often lack sewers, limiting drainage options. Possible solutions include:
Customized Large Water Storage Tanks: Modify the integrated control boards of multiple dehumidifiers and synchronize control with the water level controllers in the water storage tanks.
Sump + Pump: Utilize the existing sump in the basement and centrally treat water with a pump.
Direct Pump Drainage: Choose a dehumidifier with a built-in pump to pump water directly to a high-level drainage point.
Considerations for Drainage System Selection
When choosing a drainage method for an industrial dehumidifier, consider the following factors:
Installation Environment: Assess whether the site has a sewer and the relative height of the dehumidifier's location to the drainage point.
Dehumidification Capacity: Large dehumidification capacities require a continuous, automated drainage solution.
Operation and Maintenance Costs: Consider power consumption, maintenance frequency, and labor costs.
Cost Budget: Initial investment and operation and maintenance costs vary significantly between different drainage methods.

How to prevent dehumidifier drain pipe from clogging?
Ways to prevent drain clogs include:
Install a dehumidifier with a wastewater discharge system and regularly flush the sump.
Install a sedimentation tank to separate solid particles before discharge.
Inspect the drainage system regularly to remove debris.
Consider using a pump with a clog-resistant design.
How to drain the industrial dehumidifier when there is no sewer?
In environments without sewers, such as basements, the following drainage methods can be used:
1. Use a dehumidifier with a built-in pump to pump water to a high-level discharge point.
2. Install a large water storage tank to collect condensate from multiple dehumidifiers and discharge it regularly.
3. Use an existing sump to collect condensate and then use a pump to treat it.
